BARBERS CHAIR.

SPECIFICATION forming part of Letters Patent No. 476,774, dated June 14,1892.

Application tiled March 9, 1892. Serial No. 424,321. (No model.)

T all whom it may concern:

Be it known that I, GEORGE XV. ARCHER, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Barbers Chairs; and I do hereby declare the following tobe a full, clear, and exact description of the same, reference being hadto the accompanying drawings, forming a part of this specilication, andto the reference-numerals marked thereon.

My present invention relates to that class of chairs especially adaptedfor barbers use, and has for its object to improve their construction,whereby an adjustment necessary to place the occupant in the mostcomfortable position may be readily accomplished by the operation of asingle part, and also the chair may be raised and lowered to suitoperators of various heights; and to these and other ends the inventionconsists in certain novelties of construction and combinations of parts,all as will be hereinafter fully described, and the novel featurespointed out in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a longitudinal section of achair, showing my invention applied thereto; Fig. 2, a plan view of theseat-frame; Fig. 3, a vertical section taken on the line marof Fig. 2.Fig. 4 is a sectional view taken on the line 1j y of Fig. 2. Figs. 5 and6 are sectional views on the lines a h and e cl, respectively.

Similar reference-numerals in the several figures indicate similarparts.

The back 1, seat-frame 2, depending bars 3, constituting part of theforward frame supporting the foot-rest, and arms 1l are of the ordinaryor any preferred construction, the back being pivoted to the frame at 5and to the rear ends of the arms at 6, the forward ends of the armsbeing pivoted at 7 to the depending front bars 3, which latter arepivoted to the frame 2 at 8, the construction being such that when theback is tilted to the rear the depending arms 3, carrying the foot-rest,are elevated.

The base 9,011 which the chair is supported, is provided with suitablelegs 10, and the connections between this base and the seat-frame andadjusting mechanism form the subjectmatter of my present invention.

Secured to the under side of the seat-frame 2 is a spider or framecomposed of the side arms 1l, rearwardly-extending arm 12, andforwardly-extending arm 13, said arms being preferably formed integralwith the central annular portion or ring 14E, provided on opposite sideswith upwardly-projecting lugs 15 for steadyin g the operation of thelocking device, as will be described, and at the rear with lugs 16 forsteadying the movement of a longitudinally-sliding rack-bar 17, by whichthe adjustment of the chair is controlled. This bar 17 slides on the topof the spider and is prevented from lateral movement by the lugs 16 andalso by depending lugs 1S, with which it is provided, engaging the reararm 12, and its forward end isalso guided in its movements by aprojection 19 on the spider, entering a groove 20 in its side. A link 21is pivoted at one end to the forward portion of the rack-bar and at theother to the piece 50, connecting the depending bars 3, so that by theadj ustmentof theback the rack 17 is moved backward and forward and theadjustment of the chair will be accomplished.

Secured to the base 9, and preferably near its upper end, is a nut 22,in which operates the threaded standard 23, provided with an annularange 24, to which is secured by rivets or otherwise a ring 25, providedwith a series of perforations 26 near its periphery, and upon this ringthe lower edge of the annular part 14 of the spider has its bearing,constituting a swiveled support for the chair, the parts being retainedin operative connection by suitable bolts or screws 27 on the arms ofthe spider, which project beneath its edge, as shown, and prevent itsupward. movement, though they do not interfere with its being rotatedthereon.

While I prefer to make the iiange 24 and ring separate, it is obviousthey could be constructed in one piece, if desired;

On the inner sides of the standard are provided two projections 28,having verticallyextending slots, and located with the standard is avertically-movable rod 29, having a pin 30 cti-operating with the slotsin the proj ections or standard, and to the upper end of this rod isconnected a device for engaging the bar 17 and locking it, consistingot' ayoke or casting 3l, provided with a central-aperture, through whichthe bar 17 passes, the

Y laterally-extending sides projecting between the lugs 15 of the spiderand the depending arm 32 projecting downward and adapted to engage oneof the series of holes 26 in the plate 25, said arm being slightlylonger than the portion of the yoke engaging the rackbar 17. Theconnection between the rod 29 and the casting 31 is formed by extending'the rod through the lower portion of the casting and providing pins 33,engaging it on the upper and lower sides, as shown, so that the verticalmovement of the rod will cause the lifting of the yoke 31; but thelatter, which is laterally rigid with the chai r-seat, may turnindependently of said rod. The lower end of the rod 29 is provided witha screw-thread oi' the same pitch as the thread in the nut 22 in thestandard, and screwing upon itis a nut 34, pivoted on the end of thelink 35, which in turn is pivotally supported on a foot-lever 36,pivoted to the chair-base and extending outwardin position to be convenientlyactuat ed by the operator. Aspring37 encircles the rod 29,engaging at its upper end a washer 38 beneath the lugs 28, and its lowerend is supported upon a washer arranged above a pin 39, passing throughthe rod above the nut, said spring holding the rod and the locking-yokemoved downward in engagement with the rack-bar 17 and holding theprojection 32 of the yoke in engagement with one of the perforations inthe plate 25. In normal position the standard is held locked to the baseby means ot` a set-screw 40, passing through the side of the nut 22 andengaging the standard, and the tilting of the chair-back and foot-restcan be accomplished by the operator pressing on the end of lever 36, andthrough the link, nut, and rod raising the yoke 3l a distance sufcientto release the rack 17, when by manipu' lating the back the desiredadjustment can be secured, and if it is desired to rotate the chairseaton the standard a further upward movement of the yoke will disengage theprojection 32 from the plate 25, when the chair-seat and spider may berotated on the latter plate to the desired position, the yoke movingwith them independently ot` the rod,'and upon the release of the treadlethe parts will become locked in position again by means of the action ofthe spring.

Should it be desirable to change the elevation of the chair to suitoperators of different heights, it is only necessary to loosen thesetscrew 40, and the standard maybe rotated in the nut 22 in the baseand the chair-seat elevated or depressed. As the rod 20 rotates with thestandard it will be moved upward through the nut 3Jr without affectingthe position of the lever 36, and the connection formed by this nutbetween the actuating-lever and the locking-yoke or equivalent device isvery desirable, as it enables me to einploy a stationary releasing-leverconnected with a vertically-movable standard in such manner that thelatter can be adjusted without affecting the position or operation ofthe former. When the desired vertical adjustment of the standard isaccomplished, it may be locked to the base again and the tilting androtary movements of the chair governed by means of the foot-lever` asbefore described.

It is obvious that substantially the same mechanism as herein shown anddescribed could be employed in chairs in which the front is notadjustable, but the back only, the latter being connected to therack-bar 17, said rack or an equivalent movable portion being,considered broadly, a movable part governing the movement of theadjustable part of the chair.

While I prefer to employ all the adjustments herein described in mychair, it is obvious that the movable locking portion described as theyoke could be employed only to control the chair when moved on thestandard or only when the back is adjusted, or both, as shown. Again,the same eXtensible connection between the lever and the part calle-dthe yoke could well be employed in chairs having other adjustments-as,for instance, one in which the movement of a part corresponding inposition only to the yoke would cause other adjustments or operations.

Instead of supporting the nut 34 on the lever, it is obvious that ascrew could be connected to the lever and the nut formed on the rod 29.

Other similar modifications could readily be made withoutdeparting fromthe spirit of my invention. A
